The bordered-curve complement invariance conjecture for knot Floer homology

Let KYK\subset Y be a knot with complement M=Yν(K)M=Y\setminus\nu(K). The decorated curves HF^(Y,K)\widehat{\mathit{HF}}(Y,K) are curves in the punctured torus TMT_M^*, and HF^(M)\widehat{\mathit{HF}}(M) denotes the decorated curves associated to the bordered Floer invariant of MM. Complement invariance conjecture. For any knot KYK\subset Y with complement M=Yν(K)M=Y\setminus\nu(K), the decorated curves HF^(Y,K)\widehat{\mathit{HF}}(Y,K) in TMT_M^* agree with the curves HF^(M)\widehat{\mathit{HF}}(M) defined in the cited work; in particular, they are invariants of the knot complement MM. This would identify the knot Floer construction with the bordered Floer immersed-curve invariant and show that it depends only on the complement.
